Hi! I have unibody macbook last 2009 and I follow the steps to be able to create an usb with windows 7 using BootCamp. After restart the machine the usb start loading the windows 7 system to install. The main problem is when I format the bootcamp drive as Apple told in their instructions. After format I get the following error when I try to install windows 7 in the hard disk: Error 0x80300024 Any idea or know how can I solve this problem?? Thanks!! P.D: I attach images to see the error.
